For the answer to the question above, first all you have to do is have a confidence. If you are curious about their birthday's come up with a question that won't sound so weird. Like " Hi, I'm doing a research for a subject about people who are born on the same month can you help me? or something like that.
All you have to do is have some confidence so that you wouldn't sound so weird

A triangle has an angle that measures 80°. The other two angles are in a ratio of 7:13. What are the measures of those two angle

kap26 [50]

The angles are B and C.

The three angles add up to 180º
A=80º
B
C

A+B+C=180º
80º+B+C=180º
B+C=180º-80º
B+C=100º (1)

The ratio between A and B is 7/13 ; therefore:
B/C=7/13 ⇒B=7C/13 (2)

With the equations (1) and (2), we make a system of equations:

B+C=100
B=7C/13

We can solve this system of equations by substitution method:
7C/13 + C=100
least common multiple=13
7C+13C=1300
20C=1300
C=1300/20
C=65

B=7C/13
B=7*65/13
B=455/13
B=35º

Answer: The measures of those two angles are 65º and 35º.

Given the triangle below right at simplified expression that represents the perimeter in terms of x Use your expression to solve

Flauer [41]

Based on the given parameters, the value of x in the rectangle is 6

<h3>How to determine the value of x in the rectangle?</h3>

The given parameters are

Perimeter = 62

From the figure, we have

Length = 2x

Width = x + 13

The perimeter is calculated as:

P =2 * (L + W)

This gives

2 * (2x + x + 13) = 62

So, we have

2 * (3x + 13) = 62

Divide both sides in the above equation by 2

3x + 13 = 31

Subtract both sides in the above equation by 13

3x = 18

Divide both sides in the above equation by 3

x = 6

Hence, the value of x in the rectangle is 6

Solve this equation for x. Round your answer to the nearest hundredth. 0.77 = log x

Alekssandra [29.7K]

Answer:

x ≈ 5.89

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Algebra II

Exponential to Logarithmic: $\displaystyle b^m=x \rightarrow log_bx=m$

Step-by-step explanation:

Step 1: Define

Identify

0.77 = log(x)

Step 2: Solve for x

[Equality Property] Raise both sides to the 10th power: $\displaysytle 10^{0.77} = 10^{logx}$
Simplify: $\displaysytle x = 10^{0.77}$
Evaluate: $\displaysytle x = 5.88844$
